Election Admin and Security

Well-run, secure, and accessible elections are the bedrock of a functioning democracy. But American elections have not always lived up to this ideal. The 2000 presidential election, with its “hanging chads,” drew the nation’s attention to poorly-designed voting systems. The Russian attacks on election infrastructure in 2016 highlighted vulnerabilities in computerized election systems. And access to the vote has never been guaranteed — disabled voters and voters of color still face obstacles to voting. CDT advocates for policy and technology to support a democracy that works for everyone.

PSA: Mail-in Voting – Counting Every Vote

CDT believes every vote should be counted, even if it takes a while – trust in the vote by mail process is essential to ensuring that.

Watch PSA

A still from an animated PSA by CDT, discussing the power of mail-in voting and the security measures around it. Six mail-in ballots are being scanned to check for barcodes, signatures, and other built-in checks to prevent double voting.
